LED-to-LED visible light communication networks
Proceedings of the fourteenth ACM international symposium on Mobile ad hoc networking and computing, 2013Visible Light Communication (VLC) with Light Emitting Diodes (LEDs) as transmitters and receivers enables low bitrate wireless adhoc networking. LED-to-LED VLC adhoc networks with VLC devices communicating with each other over free-space optical links typically achieve a throughput of less than a megabit per second at distances of no more than a few ...

Organic LEDs Combined With Inorganic LEDs
Journal of Lightwave Technology, 2011An organic light-emitting device (OLED) is coupled with inorganic LEDs to strengthen the OLED's weak point (i.e., low luminous intensity). To this end, side-view LED bars are deployed on the sides of the glass substrate of OLED. To extract not only OLED light but also LED light from the glass substrate, a microlens array (MLA) film is attached to the ...

Not “wage-led” versus “profit-led,” but investment-led versus consumption-led growth
Journal of Post Keynesian Economics, 2015Abstract:This paper offers a critique of the concepts of “wage-led” and “profit-led” growth based on an application of the circuit of capital macroeconomic framework. Wages are shares of capital outlays sustaining production and circulation of goods; profits are shares of sales.

ACM SIGGRAPH ASIA 2009 Art Gallery & Emerging Technologies: Adaptation, 2009
In pre-war Japan, kimonos were encoded with clues indicating gender, caste, age, class, and social ranking. Geographical location defined the colors, as certain plants that produced particular colors only grow in certain regions. Silk techniques are also regional, and the difference between fine and rough silk indicated relative wealth.

LED-Temperatursensor (LED Temperature Sensor)
tm - Technisches Messen, 2007Eine einfache Methode der Temperaturmessung mithilfe einer Lumineszenzkonversions-LED wird vorgestellt. Das Verfahren wurde an einer Standard-Weißlicht-LED erprobt und weist eine Genauigkeit von ca. 2 °C auf. Es wird gezeigt, dass bei Verwendung anderer Lumineszenzstoffe die Genauigkeit signifikant erhöht werden kann.

Led Zeppelin’s Led Zeppelin IV
2005In this wickedly entertaining and thoroughly informed homage to one of rock music’s towering pinnacles, Erik Davis investigates the magic-black or otherwise-that surrounds this album. Carefully peeling the layers from each song, Davis reveals their dark and often mystical roots-and leaves the reader to decide whether Led Zeppelin IV is some form of ...
